A theorem concerning the decomposition of weakly nonlinear extensions of dynamical systems. (Russian) Zbl 0568.34032
The author’s main aim is to prove that, if the linear extension $$p: (X,\pi)\to (B,\rho)$$ satisfies a certain condition of exponential type, then each nonlinear extension $$p: (X,\lambda)\to (B,\rho)$$ sufficiently close to it may be represented as a Whitney sum of two extensions $$p: (X_ 1^{\lambda},\lambda)\to (B,\rho)$$ and $$p: (X_ 2^{\lambda},\lambda)\to (B,\rho)$$.
